BURLINGTON, Mass. (AP) -- Mitt Romney's presidential campaign has canceled an event planned for Sunday, Sept. 16, in Pueblo, Colo., because of the crash of a small aircraft at the Pueblo airport.

Romney campaign spokesman Rick Gorka says the crash at Pueblo Memorial Airport is under investigation and the campaign did not want to interfere with the investigation or any emergency response efforts. The event was scheduled to be held at an aircraft museum near the airport.

Colorado is among a handful of battleground states being heavily courted by Romney and President Barack Obama.

Media reports in the state said that an experimental plane crashed at the airport Sunday morning, killing one person and closing two runways.
